Abstract
Fear of weight gain may play a central role in maintaining eating disorders (EDs), but research on the role of fear of weight gain during cognitive behavioral therapy (CBT-E) for binge-spectrum EDs is sparse. We examined changes in fear of weight gain during CBT-E for binge-spectrum EDs. We investigated whether fear of weight gain predicted loss of control (LOC) eating or weight change.
Participants (N = 63) were adults of any gender recruited as part of a larger trial. Participants received 12 sessions of CBT-E, completed diagnostic assessments at pre-, mid-, and post-treatment, and completed brief surveys before sessions.
Fear of weight gain decreased across treatment, moderated by diagnosis. Those with bulimia nervosa spectrum EDs (BN-spectrum), compared to binge eating disorder, reported higher fear of weight gain at baseline and experienced a larger decrease in fear across treatment. Those reporting higher fear of weight gain at a given session experienced more frequent LOC episodes the following week. Fear of weight gain was not associated with session-by-session changes in BMI.
CBT-E results in decreases in fear of weight gain, but levels remain high at post-treatment, especially for those with BN-spectrum EDs. Future interventions should consider targeting fear of weight gain as a maintaining factor for LOC episodes TRIAL REGISTRATION: NCT04076553.
Level II controlled trial without randomization.
